Cohesion Tester | Slurry Seals

The test method is used to determine the minimum cohesion of slurry seals in order to determine the setting time and the time to recirculation. The setting corresponds to the end of the irreversible coalescence of the emulsion. The setting time taken corresponds to the time between the casting and setting of the material.

The twisting torque is measured on five samples of the same material at appropriate intervals after casting. Since EN and ASTM / ISSA methods are quiet different, two distinct references are proposed.
